Constantine I, King of Greece (August 2, 1868, Athens – February 11, 1923, Palermo). The first-born son of George I and of Russian Grand-Duchess Olga, Constantine married Princess Sophia of Prussia in 1889 and thereby became a brother-in-law of Kaiser Wilhelm II, whom he personally admired along with his authoritarian rule. As the commander in chief of the Greek army, he had subsequently been partly responsible for a serious defeat during the Greco-Turkish War of 1896/1897. Suspected of nepotism, Con…

Alpine Warfare When the Italian declaration of war was delivered on May 23, 1915, it plunged Austria-Hungary into a desperate situation. While this move by Italy did not come unexpected, almost all the forces of the Danube Monarchy were tied up on the Eastern Front and in the Balkans, where the Central Powers had in that year taken the initiative. Only weak, improvised forces were available to secure the 600-km long border with Italy, among them almost 30,000 militia reserves (Standschützen). By t…

Tsingtao (Qingdao) Administrative center of Jiaozhou, a German colony established on the northeastern coast of China in 1897. It was militarily important as the base for their East-Asia Cruiser Squadron. Unlike the other German colonies, Tsingtao was controlled by the Reich Naval Office rather than the Reich Colonial Office. Tsingtao later lost its strategic significance when the Imperial Navy transitioned from war cruisers to a battleship-fleet based doctrine. Still, the 500 km2 protectorate of Jiaozhou (Kiautschou) remained important as the economic and political…

Armed Forces (Italy) The defense of the Italian Kingdom proclaimed on February 18, 1861, was the duty of the Royal Army and the Royal Navy. The King was nominally the supreme commander of the military in peacetime, but the chiefs of the General Staff and the Admiralty functioned as the de facto Supreme Command in time of war. Italy’s new national army evolved from the Piedmontese Army that had fought in the Wars of Independence. Though gradually restructured into the Royal Italian Army, it maintained its traditional character, especially the imprint of…

Gallipoli A peninsula bordering on the Dardanelles. The military conflict at Gallipoli was a direct consequence of the failed naval operation in the Dardanelles. The British leadership wished to make up for this reverse by conducting a landing operation on the northern Turkish coast. This was remarkable inasmuch as it had always argued in front of the War Council that the great advantage of the Dardanelles operation lay in the fact that it could easily be called off in the event of a failure. It …

Troop Strength The initial numbers of soldiers mobilized for immediate wartime service. The peacetime strength of the individual armies before 1914 provided the foundation for troop strength in the war. A cadre of commanders for reserve units and an attachment of reservists for these troop units were included in their mobilization plans. This would make it possible to raise units to wartime strength once the mobilization was begun. The troop strengths planned in the event of war, and the troop str…

Armed Forces (United States) During the First World War the armed forces of the United States were crafted by national politics. The Russian Provisional Government of 1917 had promised resolutely to continue the war in the East. On the Western Front, the Germans were unequivocally on the defensive. In no way was America itself directly threatened. Nevertheless, the pattern developed in the World War would guide the United States in 20th century warfare. Politics would determine the strategy, the org…

Fortresses Sites provided with permanent, artificial reinforcement, so as to protect them from capture by the methods of field warfare. For this reason, the battle for fortresses was always given a particular designation as “fortress warfare,” to distinguish it from “field warfare,” or war as waged by mobile field forces. The technical design of fortresses closely paralleled developments in artillery, which made tremendous advances during the 19th century (introduction of guns made from drawn steel, long-range howitzers, armor-piercing shells).…

Armed Forces (Dominions) The settler colonies of the British Empire (Australia, New Zealand, Canada, and South Africa) had already acquired the status of dominions prior to 1914, as part of a constitutional development towards full independence. Self-determination in domestic matters had already been granted to Canada in 1867, to Australia in 1901, to New Zealand in 1907, and to South Africa in 1910. The British declaration of war on Germany in 1914 was binding for all dominions, since London still…

Palestine Front After the failure of the two Turkish/German expeditions against the Suez Canal (in January/February 1915 with 18,000 men and 5,000 camels, and in July/August 1916 with 16,000 men, including Austro-Hungarian contingents, and, again, 5,000 camels), by the beginning of 1917 the Ottoman Empire had been forced to evacuate the Sinai Peninsula. The Turks chose the Gaza – Tel el Sheria – Beersheba line, a front of 50 km, for their defense of Palestine. The mixed units on the ground were co…

Gaza A town in southwest Palestine. After the failure of their assaults against the Suez Canal during 1916, Turkish forces withdrew to the Gaza – Tel el Sheria – Beersheba line, which barred access to Palestine and Jerusalem. In the spring of 1917, British troops under General Sir Archibald Murray launched a surprise attack on the line from the Sinai. The British were quickly repulsed in this First Battle of Gaza of March 26–27. The renewed attack on April 17 (Second Battle of Gaza), confronted a…

Caporetto Town on the Isonzo River (modern Kobarid, Slovenia). During the battle fought in the Julian Alps from October 24 to November 9, 1917, Austro-Hungarian and German forces brought about the collapse of the Italian Front on the upper Isonzo and forced the Italians to retreat behind the Piave River. The Battle of Caporetto is also known as the Twelfth Battle of the Isonzo. In August/September of 1917 the Eleventh Battle of the Isonzo and the capture of the Bainsizza Plateau by the Italian Second Army plunged the Austro-Hungarian forces into a profound c…
